2 Claims. (01. 184-65) My application relates to oilers particularly ofthe type which is adapted to be used on outdoor applications which haveto withstand a wide range in temperature and in which the oilerreservoir is made of a material such as plastic or glass which isadapted to be secured to a metallic base.

An object of my invention is to provide an improved oiler.

Another object of my invention is to provide an improved oiler having alubricant reservoir formed of one material and a base formed of anothermaterial and to provide a suitableeseal between the adjacent surfaces ofthe reservoir and the base which will remain effective under a widevariation of temperatures.

Further objects and advantages of my invention will become apparent andmy invention will be better understood from the following descriptionreferring to the accompanying drawing, and the features of novelty whichcharacterize my invention will be pointed out with particularity in theclaims annexed to and forming part of this specification.

The figure in the drawing is a side elevational view, partly in section,of an embodiment of my improved oiler.

Referring to the drawing, I have shown an embodiment of my improvedoiler construction in which a reservoir cup I of suitable material, suchas glass or plastic, is formed with an outwardly extending base flange 2adjacent one end thereof and adapted to be closed at the other end byany suitable cover, such as a screw 'cap 3 which threadedly engages thisend of the cup. A metal 1 base 4 is provided having an annular pocket 5arranged over the flanged end 2 of the cup I and is formed with aninturned retaining flange 6 extending over a portion of an end of thecup flange with a sealing space between the base and sealing arrangementwith the lower face of the a cup flange 2 and with both the inner andouter side surfaces of the annular pocket 5, thereby forming a resilientlubricant seal between the joints of the reservoir cup I and the oilerbase 4. With this construction, the reservoir may change in dimensiondue to temperature changes and aging, and the synthetic sealing washerl, which has cold-flow properties, will be biased against the base ofthe cup flange 2 and the sides of the pocket 5 to provide an effectiveseal even under these varying conditions. A suitable central feedopening is formed in the base 4 and a lubricant feed tube 9 is spun overand brazed, welded, or

otherwise suitably secured in the opening in the base 4 to provide forfeeding lubricant from the reservoir cup to a bearing or otheroil-lubricated device as desired.

While I have illustrated and described a particular embodiment of myinvention, modifications thereof will occur to those skilled in the art.I desire it to be understood, therefore, that my invention is not to belimited to the particular arrangement disclosed, and I intend in theappended claims to cover all modifications which do not depart from thespirit and scope of my invention. 7

What I claim as new and desire to secure by Letters Patent of the UnitedStates is:

1. An oiler including a reservoir cup having an outwardly extending"flange adjacent one end thereof, a base having an annular pocketarranged around said one end of said cup with an inturned retainingflange extending over said cup flange with a sealing space between saidbase and the adjacent end of said cup, and means including a sealinggasket in said base pocket between said cup flange and the bottom ofsaid pocket and a spring washer arranged for biasing said gasket intolubricant sealing engagement with a face of said cup flange and a sideof said base pocket for sealing the joint between said cup and saidbase.

2. An oiler including a reservoir cup having an outwardly extendingflange adjacent one end thereof, a metal base having an annular pocketarranged over said one end of said cup with an inturned retaining flangeextending around said cup flange and a sealing space between said baseand the adjacent end of said cup flange, means including a resilientsealing gasket of lubricantresisting synthetic rubber material in saidbase pocket between said cup flange and the bottom of said pocket with aflexible frusto-conical spring washer arranged between said gasket andsaid base biasing said gasket into lubricant-sealing engagement with aface of said cup flange and the sides of said base pocket for sealingthe joint between said cup and said base, means including a lubricantfeed tube extending from said base for feeding lubricant from saidreservoir cup, and

- 3 4 a cover over the end of said cup awayfrom said UNITED STATESPATENTS base.
